Group Progress
This week was the mid-demo presentation, and we worked on creating sample data to show for it. We first worked on the phase vocoder to change the song speed multiple times throughout one song. We also worked on getting the gyroscope data from the Bluefruit to our app. Unfortunately, we found out that the data being sent to the app was not usable at all. The numbers made no sense and weren't even consistent. We did not realize this until the day before our demo presentation, so we had to create something very quickly using the gyroscope on the phone. With this we were able to get consistent readings and even show the RPM.
Individual Progress
Robert Keller: Created a miniature demo that showed that our phase vocoder could change speeds multiple times throughout one song by breaking the song into different windows and manipulating those. Quality of sound, however, was relatively poor, and he is looking into how to fix that issue. Advice from Professor Sullivan was to look into analyzing the song frame by frame instead of breaking it into chunks. He has started looking into how that is manageable and what implementations have already been created.
Julian Trulear: Helped Rob with the phase vocoder demo and how it functioned. Mainly worked with David in order to get the data from the LSM9DS0 to the Android phone. Unfortunately, the data that was being sent was not usable, so is now working with Arduino to check and make sure that the LSM9DS0 isn't broken. Has also been checking solder connections as they have been coming apart from time to time, and that is a priority fix. Worked with David on creating the, hopefully, temporary gyroscope app that uses the phone's gyroscope.
David Yuan: Worked with Julian on the Android app and receiving data. With the LSM9DS0 not sending correctly, decided to use the phone's gyroscope as a backup plan. From there, he was able to calculate how we would use that data to get the RPM of the bike. Also touched up on the UI of the gyroscope app to make it fit on screen a little bit nicer. He was also the one that got the bike for us to start working on.
Goals for Next Week
Have the phase vocoder output a nicer sounding music signal and start working on analyzing it to make it more real time. Experiment with the LSM9DS0 and Bluefruit with Arduino to make sure that they are sending the correct data. Make sure that the LSM9DS0 is wired correctly with the Bluefruit as a TA mentioned a missing capacitor. Have the UI of the application that we eventually use to be cleaner and display only the information that we need.
